Secondary water supply energy-saving control method and device
The invention provides a secondary water supply energy-saving control method and device. The method comprises the following steps that S1, the water pressure value P1 of the most unfavorable point and the water pressure value P2 of a water supply outlet are obtained in real time; s2, judging whether the current period is a water consumption peak period or not, and if yes, taking a peak period set value as a comparison value; if not, the flat peak period set value serves as a comparison value, and the comparison value comprises the most unfavorable point water pressure set value P1'and the water pressure set value P2 'at the water supply outlet; s3, first pump power adjustment is conducted according to the ratio of the most disadvantageous point water pressure value P1 to the most disadvantageous point water pressure set value P1 ', and S4 is conducted after time delay t; s4, the pump power is adjusted for the second time according to the ratio of the water pressure value P2 at the water supply outlet to the water pressure set value P2 'at the water supply outlet. By means of the double-pressure balance control method, it is guaranteed that a user can have sufficient water, meanwhile, the running power of a motor is reduced, and energy consumption of a pump room is saved.
本发明提出一种二次供水节能控制方法及装置，方法包括以下步骤：S1，实时获取最不利点水压值P1和供水出口处水压值P2；S2，判断当前是否为用水高峰期，若是，将高峰期设定值作为比较值；若否，将平峰期设定值作为比较值，比较值包括最不利点水压设定值P1’和供水出口处水压设定值P2’；S3，根据最不利点水压值P1与最不利点水压设定值P1’的比值进行第一次泵功率调节，延时△t后进行S4；S4，根据供水出口处水压值P2与供水出口处水压设定值P2’的比值进行第二次泵功率调节。本发明利用双压力平衡控制方法，既保证用户能有充足的用水，同时减少电机运行功率，节约泵房能耗。
